Pump outside range
When the pump operation function is disabled the pump will stop if
the outdoor temperature is higher than the value set by the Space
heating off temperature [4‑02] or if the outdoor temperature drops
below the value set by the Space cooling off temperature [F‑01].
When the pump operation is enabled, the pump operation is possible
at all outdoor temperatures.
# Code Description
[4.9] [F-00] Pump operation:
▪ 0: Disabled if outdoor temperature is
higher than [4‑02] or lower than [F‑01]
depending
on heating/cooling
operation mode.
▪ 1: Possible at all outdoor
temperatures.
Increase around 0°C
Use this setting to compensate for possible heat losses of the
building due to the evaporation of melted ice or snow. (e.g. in cold
region countries).
In heating operation, the desired leaving water temperature is locally
increased around an outdoor temperature of 0°C.This compensation
can be selected when using an absolute or a weather dependent
desired temperature (see illustration below).

Overshoot
This function defines how much the water temperature may rise
above the desired leaving water temperature before the compressor
stops. The compressor will start up again when the leaving water
temperature drops below the desired leaving water temperature.
This function is ONLY applicable in heating mode.

Antifrost
Room frost protection [1.4] prevents the room from getting too cold.
For
more information about room frost protection, see
"8.4.2 Room" on page 46 .
8.4.6 Tank
Tank setpoint screen
You can set the domestic hot water temperature using the setpoint
screen. For more information about how to do this, see
"8.3.5 Setpoint screen" on page 43 .
Powerful operation
You can use powerful operation to immediately start heating up the
water to the preset value (Storage comfort). However, this consumes
extra energy. If powerful operation is active, will be shown on
the home screen.
To activate powerful operation
Activate or deactivate Powerful operation as follows:
1 Go to [5.1]: Tank > Powerful operation
2 Turn powerful operation Off or On.
Usage example: You immediately need more hot water
If you are in the following situation:
▪ You already consumed most of your hot water.
▪ You cannot wait for the next scheduled action to heat up the DHW
tank.
Then you can activate DHW powerful operation.
Advantage: The DHW tank immediately starts heating up the water
to the preset value (Storage comfort).
